Transmission Help

rm80, rm85 86-14
 early rm125, 89-91

Tired of rebuilding competition transmissions every few months?
Held back by sloppy shifting?
Miss those "lazy" shifts when trail riding?

Gear and fork damage is usually caused by missed shifts.
It's like a sledgehammer in there when the dogs skip out of their slots and sloppily re-engage - and bottom out the clutch basket damping springs. That's how clutch baskets and gear teeth suddenly shear - Mechanical Shock.

The F-Pro Shift Detent Arm has a tough microbearing to reduce rotational friction in the shift mechanism - letting the lever, shift star, forks and gears move quicker - all with the benefit of getting the gears more fully engaged in less time - and MAGIC - missed shifts are almost eliminated - Works with undercut and non-undercut gears.

Sure is cheaper than splitting the cases every few months of competition and throwing in a couple handfuls of money.

Installation: about an hour - the arm and spring sit right under the clutch basket assembly.

It won't fix a worn transmission, but it will help a good transmission from going bad.

Hey Marc,

Raul put the cover on the drz400sm this morning, and I thought these photos were probably better quality than his phone-camera thingy. Thanks for making great product, and having great people work for you. The bike runs killer, Raul did a fantastic job tuning it, and I'm loving riding it. Need to get back on the bicycle, though...
Later, Tim

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.
The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
Edited to the tunes of Chemical Residue by Herbie Hancock.

Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
